STIRRUP.

SPECIFICATION forming part of Letters Patent No. 223,690, dated January20, 1880.

Application filed June 21, 1879.

the annexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a perspective view of myimproved stirrup, showing its parts disengaged. Fig.

2 is a vertical longitudinal section thereof with the parts engaged.Fig.3 is an edge view, showing the stirrup-sections disengaged; and Fig.4 is a bottom view, showing the latchspring.

This invention has for its object the improvement of that class ofstirrups that open to release the foot should it hang therein when arider'is thrown; and the nature of the invention consists in a stirrupmade in two sections, one of which-the side baris pivoted to the otherto swing at right angles to the plane of the stirrup, and has at itslower end an L-shaped groove or notch adapted to receive acorrespondingly-shaped tenon or tongue on the tread-plate, andmaintained in engagement therewith by means of a spring recessed in theunder side of the tread-plate,

and engaging at its free end a notch in the lower end of theswingingside bar, as hereinafter shown and described.

In the annexed drawings, the letter A designates a metallic stirrup notdiffering in shape from those in common use, and consisting,essentially, of a foot-plate or tread, a, two side bars, I and c, and around or rounded connecting-bar, d, for the stirrup-leather. The sidebar I), tread a, and bar 01 are cast or made in one piece, and the sidebar 0 in a second piece. Extending through the connecting-bar d is astrong bolt, e, upon which the side bar 0 is journaled as upon aspindle, so as to vibrate in a plane at right angles to that of thestirrup.

The tread or foot-plate has upon its end an L-shaped projecting tenon,f, the upper and lower horizontal edges of which are concentrio arcs ofcircles described by a radius from ment.

the center of bolt 0 to said edges. The tenon f has one of its brancheshorizontal and the other vertical as shown in Fig... 2, and extending upabove the plate a. The swinging bar 0 has formedinitacorrespondingly-shaped groove, g, adapted to receive the tenon f,but

in no way binding thereon. 'Ihus,while the said bar has free vibrationrelative to the body of the stirrup and in a plane at right anglesthereto, it is incapable of all other displace- In the lower end of theswinging bar 0 is a spring frictioncatch, consisting of concave orangular depression or recess 7;, in 6 5 which is received acorrespondingly-shaped head, i, of a spring-latch, j, recessed in theunder side of the tread, and of sufficient strength to hold the sectionsof the stirrup together under ordinary circumstances.

Should a horseman be thrown and his foot remain entangled in thestirrup, the spring will yield, its head escape from the recess of theswinging bar, and the latter, being thus released, will vibrate upon itsbar and release the foot.

I am aware that a'sectional stirrup has been made with its branchpivoted at its lower end to revolve outward and downward in the plane ofthe stirrup but.[ do not claim such 0011- structi'on.

What I claim as new, and desire to secure by Letters Patent, is-

l. A sectional safety-stirrup having one of its side bars pivoted at itsupper end to swing at right angles to the plane of the stirrup, andengaging with a spring friction-catch, substantially as specified.

2. In a sectional safety-stirrup, the part consisting of the tread a,side bar I), and connect- 9o ing-bar d, the through-bolt 0, extendingthrough bar (1, the side bar a, vibrating at right angles to the planeof the stirrup on said bolt 0, and provided with L-shaped notch g andL-shaped tenon f, fitting in said notch, subtantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
